Page 4: Important Safety Information
IMPORTANT SAFETY INFORMATION Read and understand these instructions prior to use. These operating instructions are not a substitute for proper training in the use of this equipment. High voltage systems present serious hazards, including the risk of death or serious injury due to arcing, thermal burns and electrocution. -
Page 5: General Description
GENERAL DESCRIPTION The DVM-80UVM is a high accuracy digital voltmeter and phasing set designed to measure voltages up to 40kV and up to 80kV when used with a pair of add-on resistors. The DVM-80UVM includes an elbow test point reading feature as well as a peak hold feature. -

Page 7: Operating Instructions
OPERATING INSTRUCTIONS The DVM-80UVM requires one 9V lithium or alkaline battery, which powers the unit and activates the backlight. The meter will shut off automatically a few minutes after the display reads zero, but not while voltage measurements are being made. The DVM-80UVM includes an elbow test point reading feature, which is displayed by a blinking decimal point ( . -
Page 8: Voltage Measurements - Line-To-Ground
OPERATING INSTRUCTIONS continued the use of two person crews allows each person to operate one meter stick and maintain high safety standards. In order to make line-to-line measurements, each probe must contact an energized line. Be sure that only those probes intended for the particular application are used (see page 9). -
Page 9: Peak Hold
OPERATING INSTRUCTIONS continued 2) Measure from one elbow test point to the other. This reading will show either a high voltage reading indicating the elbows are out-of-phase or a zero or low voltage reading indicating the elbows are connected to the same phase. The out-of- phase measurement will likely not show the higher voltage expected from a phase-to-phase measurement but will be closer to the line-to-ground voltage. -

PROBES AND ACCESSORIES continued CABLE FAULT TESTER The CFT-35 Cable Fault Tester is for use only with two stick voltmeters for testing leakage CFT-35 current in underground primary voltage cables. The CFT-35 can be used on underground cables with grounded neutrals with a maximum line-to-ground voltage of 21.1kV or maximum line-to-line voltage of 36.6kV . -

8) If the reading does not return to near zero after several seconds, the cable is leaking or shorted and the test should be discontinued. Remember that all HDE voltmeters/phasers are intermittent duty devices and should be connected only as long as necessary to obtain a reading. -
Page 14: Repairs
PROBES AND ACCESSORIES continued With the DVM-80UVM, if the cable is completely shorted the meter will read the line voltage times 0.71. For a nominal 7.2kV circuit the meter will read approximately 5.1kV . Listed here are the actual cable leakage currents for voltage readings on the DVM-80UVM digital meter: Meter reading of 0.5kV = 8uA Meter reading of 1.0kV = 16uA Meter reading of 2.0kV = 31uA... -
